well I didn't try it in an autorun.ini file or so..
but in a command line for a shortcut (.lnk file) something like
Code:
F:\tools\bsplayer\bplay.exe "F:\Roswell.avi" -stime=300
works perfectly on my computer
In a bsi file, I'm not sure this is possible... at least I don't know such an option and I can't see it in the bsplayer\doc\ini_files.html file
